I have only played a little bit with TB in a 223. 8 grains with a 50 grain Horn SPSX is doing about 1400 fps. Nice and quiet and very accurate in mine. TB is easy to play with, from full to the top to as low as still gets the bullet out the barrel it is very safe to experiment with. Basically you just have to decide what velocity you want, work to that, then play a little with OAL and powder charge around that speed to get real tight groups.
